Lockheed Senior Prom

Based on the company's Have Blue demonstrator, the six Senior Prom vehicles proved successful in testing conducted at Area 51 in the late 1970s; despite this, the aircraft was not selected to enter production, and the program was terminated in the early 1980s.

Following the success of the test program for the Lockheed Have Blue stealth technology demonstrator aircraft, the United States Air Force awarded a contract to the Lockheed Advanced Development Projects division—the "Skunk Works"—for the development of an unmanned aerial vehicle, intended to act as the prototype of a cruise missile, that would apply the Have Blue's faceted design in order to reduce the radar cross section of the missile by deflecting electromagnetic waves from radar transmitters away from their source, instead of directly back at the radar set's antenna.

[1] The program began in 1977, with a reported budget of USD $24,000,000;[2] the design of the aircraft was closely based on that of Have Blue, except scaled down.

[3] Intended for launch from Lockheed DC-130 Hercules drone launcher aircraft, the original configuration of the Senior Prom vehicle included winglets and a ventral fin; the aircraft was later modified to include a V-tail and more slender wings, closer in configuration to the F-117 Nighthawk stealth fighter.

[5] The Senior Prom vehicle was intended to be expendable; however, it was modified to be reusable before testing commenced, with a ballistic parachute and inflatable landing bag located under the fuselage.
